Elasto-Plastic Deformation of Colony Boundaries in Pearlite Microstructure by Finite Element Analyses

Article Preview

Abstract:

Elasto-plastic tensile deformations in multi-colony structures are studied by finite element analyses to investigate how the deformation in multi-colony structures influence the strain concentration around colony boundary. The results obtained from plastic strain distributions show that plastic strain concentrates around colony boundary when there is a large difference of deformation between adjacent colonies and around the point where boundaries of differently aligned colonies meet.
